Effects of GSM modulated radio-frequency electromagnetic radiation on permeability of blood-brain barrier in male & female rats

Research RF Safe Research Library Jan 1, 2016

This rat study examined whether pulse-modulated 900 MHz and 1800 MHz RF exposure affects blood-brain barrier permeability using Evans blue dye. The abstract reports increased permeability in male rats at both frequencies (stronger at 1800 MHz) and in female rats at 900 MHz but not at 1800 MHz. The authors suggest mobile-phone-like RF exposure could increase blood-brain barrier permeability under non-thermal conditions, while noting that further mechanistic studies are needed.

RF Shielded Hat for Protecting Cameraman from EMF Exposure

Research RF Safe Research Library Jan 1, 2014

The paper describes the development of RF-shielded hats using a microwave absorbing sheet intended to reduce EMF exposure to a cameraman’s head. Three hat designs are described, and measurements are planned/performed in an anechoic chamber using a wireless video camera operating around 1.9–2.7 GHz, including a 2.45 GHz signal condition and a sham condition. The abstract does not report quantitative results on whether exposure was reduced.

Electromagnetic fields act via activation of voltage-gated calcium channels to produce beneficial or adverse effects

Research RF Safe Research Library Jan 1, 2013

This narrative review argues that non-thermal biological effects of extremely low and microwave frequency EMFs may be mediated by activation of voltage-gated calcium channels (VGCCs). It cites 23 studies in which VGCC blockers reportedly block or reduce diverse EMF effects and proposes downstream Ca2+/calmodulin-dependent nitric oxide signaling. The review discusses both potential therapeutic effects (e.g., bone growth stimulation) and potential adverse effects via oxidative stress pathways, including a reviewed example of DNA single-strand breaks.

Mobile phone use and cancer

Research RF Safe Research Library Jan 1, 2004

This narrative review discusses potential public health consequences of widespread mobile phone use and the controversy around long-term cancer risks. It states that evidence from epidemiological and experimental studies suggests long-term exposure to mobile phone emissions may be linked to a small to moderate increased risk of certain cancers, while also emphasizing that data are insufficient for a final risk assessment. The author argues that even small risks could matter at the population level and that exposure-reduction measures may be indicated given uncertainties.

20 kHz Magnetic Field Emission of Induction Cooking Heaters

Research RF Safe Research Library Jan 1, 2004

This exposure assessment measured 20 kHz magnetic field leakage from induction cooking heaters across four models and compared results with ICNIRP general public limits. The maximum reported magnetic flux density was 16 µT at a specified measurement point using two S-type pans. Field leakage depended on pan size and configuration, and finite element modeling was reported to align closely with measurements.
